PATENT me GEORGE F. SEAVER, OF HAVERHILL, MASSACHUSETTS.

IMPROVEMENT IN LASTlNG-JACKS.

Specification forming part of Letters Patent No. 131,976, dated October8, 1872.

To all whom it may concerm' Be it known that I, GEORGE F. SEAVER, ofHav'erhill, in the county of Essex and State of, Massachusetts, haveinvented a new and useful or Improved Lasting-Jack, of which thefollowing is a specification:

The object of my invention is to enable a shoemaker to apply and shapethe inner sole and perform the labor of lasting a boot or shoe withgreater facility, ease, and dispatch than by the methods heretoforeadopted; and my invention consists in a new or improved jack or devicefor supporting the last and enabling the insole to be readily appliedthereto and shaped, and the whole to be brought into the most convenientpositions for the workinan while securing the upper to the insole andast.

To enable others skilled in the art to make and use my invention, I willdescribe the manner in which the same is or may be carried into efl'ect,reference being bad to the accompanying drawing, in which- Figure 1denotes a side elevation and Fig. 2 a longitudinal and vertical sectionof the device or jack as constructed in accordance with my invention. A

In the said drawing, A denotes a circular or otherproper-shaped table,which is to be affixed to the top of a workmans bench. B is aoylindrical standard or post which extends up from the said table andcarries upon its upper end a last-pin, a, which is connected with thestandard by means of a ball, b, and a socket, c, the said ball beingmaintained in its socket by means of a clamp or other suitable device,as shown in the drawing. 0 is a curved arm whose lower end is of ahollow cylindrical form, and is so aflixcd to the lower part of thestandard B as to rotate freely around the same. D is an adjustable heador toe-block,

which is so affixed to the upper end of the arm 0 as to be capable ofbeing moved nearer to or further from the standard, as may be desirable,in order to give a proper bearing to the last in accordance with thelength thereof, or the shoe to be lasted. The bearing-surface of oneportion of the block is so formed as to be adapted to support shoes ofthe ordinary and larger sizes, while its opposite part is so made that,by reversal of the block, such is adapted to shoes of the smallest size.

Having described the mechanical construction of my invention, I willnext describe the mode of using the same.

The upper of the shoe to be lasted is to be reversed and placed with thefoot-receivin g openingdownward uponthe standard D. The insole havingbeen placed upon and tacked to the last, the latter is affixed to theheel or last-pin, which supports the last, and at the same time enablesthe workman to freely move it into any desired position, and, by meansof a knife, readily to shape the sole thereto. The upper is next drawnup around the last and a suflicient distance above the edge of the soleto form the lap, and, by means of a tack driven through the heel of theupper, is secured in position. The workman next rotates the last intothe desired position and draws over the toe of the upper, and, havingsecured it in place by means of a tack or peg, next places the toe ofthe shoe upon the toe-block, when, by rotating the curved arm, the upperand the last can then be brought into the most convenient position andthe upper readily drawn over and lapped upon the insole, and tacked orsecured thereto, the curved arm allowing the shoe to be moved into anydesired horizontal position, while the ball-and-socket connection of thelast-pin enables the last to have any desired vertical inclination.

Having described my invention, what I claim is as follows:

The improved lasting-jack, as described, the V GEO. F. SEAVER.
